要获取SortedSet中的元素数量,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<string> set1 = new SortedSet<string>(); set1.Add("AB"); set1.Add("BC"); set1.Add("CD"); set1.Add("EF"); Console.WriteLine("Elements in SortedSet1..."); foreach (string res in set1){ Console.WriteLine(res); } Console.WriteLine("Count of elements in SorteSet1 = "+set1.Count); SortedSet<string> set2 = new SortedSet<string>(); set2.Add("BC"); set2.Add("CD"); set2.Add("DE"); set2.Add("EF"); set2.Add("AB"); set2.Add("HI"); set2.Add("JK"); Console.WriteLine("Elements in SortedSet2 (Enumerator for SortedSet)..."); SortedSet<string>.Enumerator demoEnum = set2.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } Console.WriteLine("Count of elements in SorteSet2 = "+set2.Count); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... AB BC CD EF Count of elements in SorteSet1 = 4 Elements in SortedSet2 (Enumerator for SortedSet)... AB BC CD DE EF HI JK Count of elements in SorteSet2 = 7
让我们看另一个例子-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<int> set1 = new SortedSet<int>(); set1.Add(100); set1.Add(200); set1.Add(300); set1.Add(400); Console.WriteLine("Elements in SortedSet..."); foreach (int res in set1){ Console.WriteLine(res); } Console.WriteLine("Count of elements in SortedSet = " + set1.Count); set1.Clear(); Console.WriteLine("Count of elements in SortedSet (updated) = " + set1.Count); } }
输出结果
这将产生以下输出-
Elements in SortedSet... 100 200 300 400 Count of elements in SortedSet = 4 Count of elements in SortedSet (updated) = 0
